This will be my attempt to build this F-22 from plans that I am drawing up from the 3 views I have. I also used a contour gauge on a plastic kit to help me with some of the curve lines on the top and bottom.

My plans are not complete and I will be updating them as move along throughout the build. Some of the parts may change as well. Build at your own risk as parts are not complete or tested yet.

The building material will be the Dollar Tree foamboard sheet sizes 20 x 30 with a thickness of 3/8" (5mm). So, I will be laminating sheets together for the build. I will be using Gorilla Glue for most of the build. Epoxy in specific areas and Spray 77 for the laminating process.

I had a question though:
the $tree readyboard I just depapered measures 5mm's thick, its my first time using readyboard, does it come in different thickness'?

I like it though, sands a little smoother than the RCFoam depron I've been using, seems liter, definitely a little more noodely (not quite as stiff), but for a buck a sheet I can get used to it.

Joe your right! Just looked at mine and it is 5mm thick after peeling paper off. It is a little noodely but it is easier to sand. I also think it is easier to use for curved sections etc. Well anyway I was drawing my plans using the inch scale so it was 3/8" that I was thinking and not 3mm. I will make that fix on the next release (update) plans. Will post pictures throughout my build along with directions as to what I am doing.

Sorry Guys! No progress. If I continue this it will be slow going. A friend of mine decided to give me his second 70mm F-22 from Banana Hobbies. He had two of them and did not have the room for it so he gave it to me. What a sweet looking F-22 although not scale looking in certian areas but it sure flys nice and I am not complaining. I think he gave it to me to see how (mine now) will fly with the Cyclone 3300 kv motor and the Change Sun 10 bladed fan before he makes the changes to his airframe.

I will be building the twin 90mm version and hopefully get to that build late summer.

What are you talking about! Very good combination and about the maximum kv you can use on the CS10 blade fan. Have been using it in my BH F-22 for the past 4 months with great results. That is why I did not build this home made model in this thread. Hand launches with ease. Will almost fly right out of my hands on its own without a toss. The Change Sun 10 blades have been holding up just fine. Just need to make sure they are balanced.

So, you're right.
Already check the numbers and the motor only works around 1290 watts which is 8.9 watts per gram of weight.
